This assignment is to write a program to score the
paper-rock-scissors game AGAIN. Each of two players enters either
P, R, or S. The program then announces the winner as well as the
basis for determining the winner: Paper covers rock, Rock breaks
scissors, Scissors cut paper, or Draw, nobody wins. The
primary differences between this and previous two versions are
described as below:
(1) You MUST use a function to get the input value for the
players choice. The players must be able to enter either upper- or
lower-case letters. If an invalid choice is entered, the player
should be permitted to re-enter his choice immediately (before the
other player is given a chance to enter their value). The function
returns an enumerated type (e.g., Choice) that has possible three
values, ROCK, PAPER, and SCISSORS (the one you defined in the
previous version). This makes it so that the only part of your
program that pertains to the player choices that can involve
character variables is the input portion. The rest of your program
should always use variables of the enumerated Choice type.
(2) you MUST use a function, e.g., checkWinner, to compare two
choices, decide the winner, and print the result on the screen.
This means that the function takes two Choice type arguments (i.e.,
player1s choice and player2s choice) and returns nothing.
The output should be like:
Player-1, please enter your choice
